摘要：
Time Scale Modification, Mp3 Compression and random cropping are challenging problems in watermarking of audio signals. To overcome these signal processing attacks, an imperceptible, blind and secure audio watermarking algorithm is presented in this paper. The proposed algorithm calculates the watermark embedding regions (WER) based on the audio localized content analysis and then embeds watermark data in these selected regions. The selection of region of embedding is done byfinding regions which are relatively invariant to synchronization attacks. This makes the embedded watermark robust to time stretching or compressing attacks. Multiresolution decomposition of the signal using wavelet domain is used in this paper for watermarking. Experimental results validate that the algorithm is robust to Time Scale Modification, Mp3 Compression and other audio signal processing attacks and maintains perceptual transparency to an accepted level with SNR above 30dB.
